The steam Apparatus, of which the following is a speciin the hot water from the heater passing upfication. ward, being separated from the water in the My invention relates to apparatu'sforheatchamber E, is delivered in the expansioning by the circulation of hot water or other drum above the water, where it condenses, fluid, particularly adapted for use in railwaycoming into contact, as it does, with the sides cars. and top of the expansion-drum and the water The object of my invention is to provide a therein. The steam thus delivered into the means for supplying a solid column of water expansion-drum condenses very quickly and r5 from the expansion-drum down through the exerts no appreciable pressure upon the downflow-pipe and for turning the hot water water therein. hen the heater is in vigorwhich rises from the heater into the downous action, a portion of the steam may acl'low-pipe rather than causing the heated company the water a short distance downwater to mingle with'the water in the eXpanward from the chamber E into the pipe G sion-drum. I accomplish this object by before it escapes, and it is for this reason that means of the mechanism illustrated in the I preferably extend the pipe G below the accompanying drawings, in which chamber E at a distance of about a foot;

The radiator-pipes A are supplied with So far as I am aware, no other heating apwater by the downflow-pipe B and are conparatus is provided with a means for sepa nected by the pipe C with the heatingdrum rating steam from the water at the highest V or with a Baker heater, which may be subpoint of the circuit or for conveying steam stituted in place of the heatingdrum V, if deto the space at the top of the expansion-drum sired. The expansion-drum D connects with the downflow-pipe B by means of the fitting without passing through the water in said T, which fitting is preferably provided with a drum.

By my apparatus I do away with the semicircular opening t, communicating with method heretofore employed in hot-water- 0 the expansion-drum D and with the pipe B. circulating systems of heating the water in IVithin the fitting T,'I arrange a chamber E, the expansionlrum, as it requires a concommunicating with the pipe F, extending siderable time to change the temperature of into the expansion-chamber D above the the water therein and the flow of hot water to water placed therein, and also communicatthe car in said method is always delayed on 5 ing with the pipe G, extending downward that account.

(Not shown.) The spurs are openedat their ends'farthest from the fitting L, allowing the steam to pass through and to enter pipes N and O, which envelop said spurs and which are closed at their ends farthest from said fitting and which are secured to said fitting, communicating with the chamber R therein, said chamber R communicating with a pipe Q, which carries off the water of condensation from the pipes enveloping said spurs. The pipe 0, communicating with the radiators, carries the water ofcirculation into the drum V, where it circulates and passing therethrough in contact with the pipes N and 0, through which the steam from the spurs passes, and out through the pipe H, conveying the heated water and such steam as may be generated to the fitting T.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a hot-water heating apparatus, a heater; radiator-pipes an expansion-drum; a downflowpipe; a fitting provided with a chamber; a pipe leading from said chamber to the expansion-drum; a pipe leading from said chamber to the downfiow-pipe; a pipe leading to said chamber from said heater; a means for conveying water from the expansion-drum to said downflow-pipe, substantially as described.

2. In an apparatus for heating by the circulation of hot water, a heater; an expansiondrum; a downfiow-pipe; radiator-pipes; a pipe-fitting; a pipe for conveying the water heated in said heater to said fitting; a means in said fitting for separating the steam from the water; a pipe for conveying the separated steam to the expansion-drum at a point above the water therein; a pipe for conducting the hot water from said fitting into the downflow-pipe, substantially as described. 7

3. In a hot-water heating apparatus, a heater; radiator-pipes; an expansion-drum; a downflow pipe; a pipe-fitting connecting with said downflow-pipe near said expansion-drum; a pipe for conveying hot water from said heater to said fitting; a means in said fitting for separating the steam from said hot water; a pipe for conducting the steam thus separated to the expansion-drum above the water therein; a pipe for conducting the water from said fitting to said downfiow-pipe, substantially as described.

4. In a hot-water heating apparatus, a downfiow-pipe; a fitting provided with a heater; an expansion-drum radiator-pipes a chamber and with a passage-way communicating with the expansion-drum and with the downfiowpipe a pipe communicating with said chamber and extending into the space above the water in said expansion-drum; a pipe also communicating with said chamber for conveying the hot water from the heater to the chamber; a pipe for conveying the hot water from said chamber into the downflowpipe substantially as described.

5. In a hot-water heating apparatus radiator-pipes a downfiow-pipe connected therewith; an expansion-drum; a heater consisting of a drum; a fitting connected with said drum a steam-chamber in said fitting to .which steam is conveyed; a series of spurs communicating with said steam-chamber; a series of pipes enveloping said spurs respectively; a drip-chamber in said fitting to which said pipes are connected; a means for conducting the water of circulation to said drum and per.- mitting the same to circulate in contact with said pipes; a pipe for conveying the water of circulation from said drum to a fitting attached to the downfiow-pipe a means in said fitting for separating the steam from the hot water; a pipe for conducting the steam from said fitting to the space in the eXpansiondrum above the water therein; a pipe for conducting the hot water from said fitting into the downflow-pipe, substantially as described.
